Customers who had bought the McLaren when it was 591 hp, freely got it upgraded to the more powerful version, well at least that's what happened where I live, so I'm not sure if this page is even needed anymore

@Viking,thanks,it has been said that in the flesh the car is far more impressive than any photo!! Mine has just come back from its platfrom 10 upgrade,this makes all the cars up to current 2013 spec with the 625ps and upgraded mapping on the gearbox.I couldnt believe another 25ps would make the car feel quicker,but with the quicker gearbox as well its now even more balistic and even tiffney dell has said its made a massive difference(he was talking about the spider,but still the same spec car).I would think the track times will fall again next season as the magazines start testing the new model year,we will see !!

This car's picture belongs on a 12 year old boy's bedroom wall, it looks outrageous and it's name is comprised of a bunch of letters, numbers, and symbols that mean absolutely nothing. Jeremy Clarkson from top gear says it sounds like it's named after a fax machine. The car's name matches it's character, really technical and mathemetic.

Wow, I finally have seen one of these McLarens in person. I followed one up Route 29 in Napa California on my way to work the other day. Absolutely beautiful exotic. Wide, low, and exotic looking. Tim your car has great styling, very nice.

I'm so glad to read that lol.
If i'm lucky, i'll do a trip to Europe next year(July) to visit some race tracks and watch some graet cars :)
I would love to visit Yorkshire and admire your MP4-12C, or if u'r lucky the new F1 mate :).

@phavyarden,pm me if you are ever in yorkshire it would be my pleasure.Maybe by then i might have the new F1,its debue is in paris on the 29th september,but i am one of the lucky ones that gets a preview at the MTC first.A few people have already seen stills at pebble and the gooding auction and its very concept like and 20 years in the future with active aero pulling over 2G lateral acceleration,the F70 will this time be blown away.None of the 458/12c fixed comparisons.Mclaren are on a mission this time and are for warned !!!

@tim if I haven't mentioned it before, you have an extraordinary car. Very groovy. I haven't even seen a McLaren in person, and certainly have never driven one. Keep us all informed on what it is like to own one. :)

@sitetalker,very astute,the new quote in the Mclaren suppliment handbook for the 2013my upgrade is 26.5 seconds to 300kph,this has yet to be proven as the upgrade hasnt been impimented yet,but i think given the previous results this will be a formality!

the 12c does very well to get to 250km/h in less than 15 seconds. don't you think that 31 sec do 300km/h is a bit long? it should be closer to 27.0 I think. The upgraded one would beat the lap record @ LS :)

Looks like the 12c is now showing its true colours at Laguna seca,all the minor problems are now sorted.I wonder how much quicker it would have been with the 25hp and gearbox upgrade that are coming as a free upgrade in 6 weeks?

my2013 out 1st oct,to get a 25ps upgrade,this will also be fitted free of charge to all current cars,a first in manufacturing history i think,but something that was promised to owners from the start. 615 HP
